CAR-ROOF.

Specification of Letters Patent.

rammed rei). e, isis.

' To all 'whom it may concern Be it known that ive, HENRY J. SMALL, of San Francisco, inthe county of San Francisco and State of California, and OT'ro B. Sononiviir, of Sacramento, in the county of Sacramento and State of California,have jointly invented a certain new and`useful `Impr-eminent in Car-Roofs, of which improvement the following is a specification.

(iur present invention relates to .metallic roofs, which are inore particularly designed for use in railroad cars, biitare also adaptable for application in other structures, and are of the general type exemplified in Letters Patent of the United States No. 986,093,

granted and issued to us under date of March 7, 1911.

The object of our invention is to provide, in a. metallic. roof of such type, improved 'nieans for eifecting. the connection ofthe ,roof sheets to the side and end plates of a car, ivhereby the access of Water to the inside of the ear Will be eiiiectually'prevented and proper ventilation of the car permitted.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings: Figure l is. a partial halfplan view of a car roof embodying oui" invention; Fig. 2, a vertical longitudinal central section; Fig. 3, a half vertical transverse section; Fig. 4, a similar partial perspective section, on an enlarged scale, on the line a a of Fig. 2; and, `l `igs- 5 and G, partial transverse sections, on a similar scale, on the lines b Z) and c c, re-

spectively, ofFig. 2.

ln the practice of our invention, ive pro vide a plurality of roof sheets or plates of metal, l, sutlieient in number for the length of roof required, and of proper length for connection, at their ends, to the side plates, 5, of a car, as hereinafter described. The roof sheets, which extend continuously across the car, are connected one to another, on

i5 their adjoining sides, by rows of rivets, la,

and are arched or curved throughout their length, transversely to the car, and a longitudinal corifiraation, 1b, is formed in each sheet, saidcorrugation. which constitutes a transverse arching of the roof sheet, diniin ishing in depth from the longitudinal center line of the roof to the sides thereof, at or near which it terminates by merging into the surface of the roof plate. rlhe corrugations, 1b, perform 'the functions of the carlines ordinarily employed, ivhich are Wholly dispensed with, and enable the roof to be self snliporting.

The upper ends of the side plates, 5, are curved slightly outwardly, in order to deflect any water that may tend to enter from the outside, and the ends of the roof sheets are bent downwardly -into vertical eaves, lc, which arc located a short distance outside f the side plates. so as to be spaced apart therefrom. and depend below the curved upper end portions thereof. The bodies of the roof sheets are located a short distance above the tops of the side plates, so as to be separated therefrom by a continuous open space. The forni and relative location of the roof sheets and side plates, as above described, will clearly appear by reference to Figs. 4t, and 6. f

The middle portions of the ends of the roof sheets are connected to the side plates b v lnnizontal rivets, G, passing through short fillers or spacing pieces, 7, interposed the forni of metal platee, doubled over at and near their tops. to be eogu al to the width of the vspace between the eaves and the side plates. but castings or foi-gings of eorrespending thickness 'may obviously be used, if preferred. At the laps of the roof'sheets, one on another, their spacing, relatively to the side plates, and their connection tlierewith, are, as shown in Figs. 5 and G, similarly maintained and effected, the fillers, at these points, being in the form of ferrules or thimbles, 7a, interposed similarly to the plate fillers, 7, but in line with the rows of rivets, l, connecting the roof sheets, the rivets, (l, passing through said fcrrules, and through the eaves of two adjoining roof sheets and the adjacent side plate, and being headed over at their ends on the latter and on the overlapjiing roof sheet. The spaces between the several i'illers, on each side of the roof. are open at bottoni to the external atmosphere, and open at top to the interior cf the car. thus affording free passage of air for the ventilation of the ear. The end roof sheets are connected to the end plates, S. of the car, by rivets, 6, passing` through fillers, 7, of the forni first speci-A fied.

The roof herein set forth is simple, strong, and inexpensive, and 1s particularly advantageous in the particulars of permitting ample ventilation of thecar, preventing the such Water is led to and discharged on thel outside of the car. Y

IWe claim as our invention and desire to secure by Letters Patent l. In a freight car, metal reeling sheets extending from eaves to eaves of the car, the ends of the sheets terminating in Vertical eaves portions located a short distance outside of the side plates, and filler blocks secured to the side walls of the car at intervals throughout the length of the car, and et a thickness equal to the space between the side walls and said bent down ends of the sheets, and meanssecuring said down turned ends to said filler blocks, whereby the roofing sheets are -supported solely from the sides ot' the ear and spaced from the top and side of said side walls with an uninterrupted Ventilating space extending throughout the length of the car between the underface of the roo'l and the top of the car wall.

2.- In a car, metal load sustaining roofing sheets extending from'eaves' to eaves of the car, the end portions of the sheets extending beyond the side walls of the car and bent downward with spaces between them and the side walls, and. means secured to said down turned ends and to the outer face of the car wall and exclusively supporting saidsheets from said wall with a Ventilating space betweenthe sheets and said side walls.

3. In a car, a roof comprising load sustaining metalV sheets extending from eaves to eaves of the car and means constituting the exclusive support ot the sheetssecured to the sides of the ear, said means supporting the sheetsv with a Ventilating space between them and the top and side of the side wall.

4. A car consisting of metal side and end walls, a roof composed solely of metal sheets extending from 'eaves to eaves with their outer ends extending beyond the side walls and bent down with a space betweenthem and the side walls, said roof being wholly supported by means connecting said bent ends to the outer face of the side walls and holding said ends away from the side walls 4and the body of the sheets away from the top of the side walls whereby a Ventilating space is maintained between the sheets and side walls. the Ventilating space between the underface of the roof sheets and. the top et the car wall being uninterrupted throughout the length of the car.

5. In a car, the combination, with vertical sheet metal side plates, ,the upper edges of' which are slightly curved outwardly, metal roof sheets extending transversely ol the car, each sheet having a strengthening rib HENRY J. SMALL. OTTO B. SCIIOENKY.
